Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Colored lines at top and bottom when tv comes on and seeing double vision in different colors at all times


If your tv is not a DLP the problem is in the convergence, try to adjust it using your original remote control go to the setting menu then to the convergence section. Adjust the red and blue convergence. you should move the red and the blue in up, down and left, right if this color does not move far enough your convergence IC is already defective. Replacing this convergence IC will solve the problem. In locating this convergence IC you should remove the back cover of your unit but be sure to unplug it before doing this. This convergence IC is attached to a large aluminum plate, it is the heat sink, and it has a marking of stk- ### followed by numbers. You can try to pull it out using a soldering iron and soldering pump but be careful you may damage the board and cause much problem to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards.

Red and green double vision


This is a convergence problem that is either poor solder connections on the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are ptentially dangerous high voltages present even when unplugged, you can fix this yourself.

Please let me know if you wish to attempt the repair and I'll supply additional details and instructions.

Double vision on my samsung HDTV 1080i


If one or more of the colors, red, green or blue have separated from each other and you can`t correct the problem using the convergence procedure as described in the users manual, that would indicate you have a convergence problem. Bad solder connections on the convergence output chips are common. If the set had a rough ride down the stairs while moving, that may have facilitated in exposing a preexisting condition. However, the most likely cause is the natural failure of one of the convergence output chips and or related components and not the move. The fix is to have a qualified technician address the problem. This is not a do it yourself job.

Double Vision


Unfortunately, the complete convergence amp board is no longer available from Samsung. But the board is available from ptscorp.com. Go to the website, get the telephone number, ask them what convergence Amp board you need and if they have it. If you know how to solder and unsolder, you can simply change the convergence amp IC's, on the main convergence board. The IC number if the IC's is STK392-040 Good Luck.
